<P CLASS=para>
<tt CLASS=literal>FieldPosition</tt> objects are optionally passed to the
<tt CLASS=literal>format()</tt> methods of the <tt CLASS=literal>Format</tt> class and its
subclasses to return additional information about the
formatting that has been performed.  The
<tt CLASS=literal>getBeginIndex()</tt> and <tt CLASS=literal>getEndIndex()</tt> methods of
this class are used to return the starting and ending
character positions of some field of the formatted string.
The integer value passed to the <tt CLASS=literal>FieldPosition()</tt>
constructor specifies what field of the returned string
should have its bounds returned.  The <tt CLASS=literal>NumberFormat</tt>
and <tt CLASS=literal>DateFormat</tt> classes define various constants
(which end with the string <tt CLASS=literal>_FIELD</tt>) that can be used
here.  Typically, this bounds information is useful for
aligning formatted strings in columns--for example, aligning
the decimal points in a column of numbers.
